The Rear Panel
Status Indicator
The yellow Status Indicator shows the unit's operational
status, as described below:
• slow flash - indicates normal operation
• rapid flash - indicates a hardware failure
For the Status Indicator's behavior during a reset to the
factory default settings, see page 4.
Power Supply Connector
A single Jack socket (PS-B) for
connection of the AXIS 2490
power supply.
The RS-485/422 port
A 4-wire RS-422/485 port (one TX pair and one combined RX/TX pair).
The RX port can be used for both RX and TX (controlled by RTS)
and can be used for half-duplex RS-485. The port can be used for:
• Full-duplex RS-422 (4-wire) or
• 4-wire RS-485 or
• Half-duplex RS-485 (2-wire)
The port is compliant with EIA RS-485 up to 1843200 bps.
Connections for RS-485/422 on Connector Block
1 - 9-24V AC or DC Power
2 - 9-24V AC or DC Power
3 - GND
4 - GND 100 Ohm (to GND via 100 Ohm resistor
5 - RX/TX -A
6 - RX/TX +B
7 - TX-
8 - TX+

Physical Connections on the 8 pole I/O
Connector Block
(Phoenix MC 1.5 - 3.81mm)
4 pins for RS422/485 TX+, TX-, RX+, RX-
1 pin for RS485/422 ground (connected to
GND with 100 ohm resistor)
1 pin for GND
2 pins for alternative power (9-24V AC or DC)
Network Connector
The AXIS 2490 is designed for 10
Mbps Ethernet and 100 Mbps
Fast Ethernet networks and con-
nects to the network via a
twisted pair category 5 cable
(10baseT and 100baseTX) termi-
nated using a standard RJ-45
connector. Supporting NWAY,
the AXIS 2490 detects the speed
of the local network segment
and varies the speed of data
communication accordingly,
between 10 Mbps and 100 Mbps.
